This study verifies the direct and indirect causal relationship of sociocultural values related to appearance effect appearance evaluation, body area satisfaction, appearance orientation, and self-esteem that are variables involved in body images. This paper is expected to empirically support the information regarding the path and the relative influence among related-variables and their relational structures. A survey was conducted on 230 women from the ages of 20 to 29 who live in Daegu and Gyeongbuk areas. The data analysis was performed through programs such as AMOS 19.0 and SPSS 19.0 for Windows. The findings are as follows: First, Sociocultural values relating to appearance affect directly body image - appearance evaluation, body area satisfaction, and appearance orientation. Appearance evaluation and appearance orientation were influenced positively; however, body area satisfaction received egative effects. In addition, sociocultural values related to appearance exert relatively stronger influence on appearance orientation. Second, among body images, appearance evaluation and body area satisfaction directly effect self-esteem; however, appearance orientation did not show any direct influence. Appearance evaluation influenced relatively higher on self-esteem. Third, it appeared that appearance evaluation directly affected Appearance orientation. Forth, sociocultural values related to appearance affect self-esteem through body images-appearance evaluation, body area satisfaction, and appearance orientation - as mediators. This confirmed the mediator role of body image between sociocultural values related to appearance and self-esteem.

This study examined the effects of the cognitive and affective country image of Korea on product evaluation and purchase intention for Korean products. The research model was developed from relevant literature based on the halo effect model and data was collected using a self-administered online survey of 772 Southeast Asian consumers from Vietnam, Indonesia, and Malaysia. The major findings are as follows. First, analysis of variance revealed that Vietnam consumers have a significantly positive perception compared to Indonesia and Malaysia, regarding the affective country image and purchase intention towards Korean products. Second, results from structural equation model showed that the affective country image has significantly positive effects on product evaluation and purchase intention, which means the affective country image is directly and indirectly connected to purchase intention towards Korean products. However, cognitive country image only has an indirect effect on purchase intention. Third, the results of comparing path coefficient among three countries showed that the direct effect is more effective for consumers in Indonesia and Malaysia, whereas indirect effect has a stronger effect on consumers in Vietnam. Academically, this study contributes to an expansion of understanding the effects of country image by empirically proving the different roles of cognitive and affective dimensions for country image. This study provides practical implications for developing marketing communication strategies for businesses that hope to penetrate Southeast Asian countries.

Defense systems are needed to prevent catastrophic failures of a power grid due to cascaded events. Cascaded events can be occurred by power flow overload. Especially, it is the most dangerous problem that overload line is outage, because it can make the power system face danger of cascaded. In this paper, vulnerability evaluation for monitoring wide are outage is proposed using by configuration information of transmission systems. This method of vulnerability evaluation is considered direct effect and indirect effect of power flow, especially overload. What is more, it can be used when the configuration of power system changes, as simple fault occurs or maintenance of facility. In the case studies, the estimation and simulation network have been testified and analysed in PSSE and C programming.
